Although the contacting pressure of the single oil scraper ring remains unchanged, the laminated property on cylinder liner is improved and the tangential force can be reduced by 40% to 50%, and decreases the friction resistance.
新设计的单刮油边螺旋撑簧油环在接触比压保持不变的前提下,明显地改善了对气缸壁的贴合性,且油环切向弹力下降40%~50%,从而降低了摩擦阻力。
The pumping induced tangential strain mainly displays compression property, its magnitude decays rapidly along with radius from the well increasing, and increases exponentially along with pumping time increasing.
切向应变主要表现为环向挤压,且其应变大小随半径增大迅速衰减,随时间增长呈指数增大。
